"The real problem we face right now on a global scale is Europe," Marchionne said.
One risk: that nations bail out of the euro, leading Germany to revert to the Deutsche mark.
"There are enough German people in this room who should be spooked by the re-creation of the Deutsche mark," he said. "It would make Germany the most uncompetitive European country on the face of the earth, regardless of the quality of the work force, which is undisputedly good."
He also said the protests that have rocked nations and roiled markets are rooted in inequality that weakens societies and is bad for business.
"Political instability is disruptive to an economy, and it discourages investment," Marchionne said. While some income inequality is natural, too much leads to an unsustainable society, he added.
"These issues call into focus the moral responsibility of our actions," he said.
He said the European sovereign debt crisis had turned the tables within his own combined company: where a Eurocentric Fiat had helped save Chrysler in 2009, Chrysler's profits and those of Fiat in Latin America are now propping up Fiat.
"In less than three years, the tables have turned as far as regional economies go. But the underlying rationale for the partnership remains the same: to create the mass and the efficiencies demanded by global competition," he said.
Marchionne said Chrysler's workers and managers had worked tirelessly to restore the smallest of the Detroit automakers and would continue to do so in the years ahead.
"All of our people, represented and nonrepresented, have worked together with unwavering dedication to bring Chrysler back from the brink," Marchionne said. He recalled touring the Jefferson North Assembly plant in Detroit prior to Fiat S.p.A.'s taking control of Chrysler in 2009 and finding it in a state of "industrial neglect."
